I3231 — The Observatory shows its own stream health: lag, dropped frames, resyncs and frame rate

✕BLOKOVÁNO vlna 1 · p3 · profil implementation · bezpečné paralelně

Part of every-surface-follows-what-changed — Every surface follows what changed in the repository by push, and a surface that does not says so.

Cíl

Add a diagnostics overlay to the Observatory (toggled like its legend) that derives from the stream it follows: frames received, last frame age, resyncs, gaps detected, and the measured frame rate of the renderer.

Proč

Proposed on 2026-10-14 as a self-observing visualisation; useful for a kiosk left running. Proposed in ADR 0216 (Every live surface follows one channel with named follow streams, and nothing polls where a stream exists) (proposed; it carries no authority until the owner accepts it). Sources: chatgpt-majordomus:c260#8.

Aktuální stav

share/ui/observatory.js has an 'i' legend toggle and status words; no counters of its own stream.

Cílový stav

The overlay's numbers are counted by the script from frames it received; nothing is typed.

Závislosti

• I3219○READY The Observatory is told what happened over the live channel, and asks only when it cannot be told

Kritéria přijetí

• A forced resync increments the overlay's resync count
• The overlay on the published replay is claimed by an interaction spec, and on /ui/observatory it is driven by cockpit-probe
